Embodiment Construction
[0014] 1. In the embodiment of the present invention, the plunger mud pump is changed to a piston isolation slurry pump, see [ figure 1 , 2 , 3, 4], between the cylinder (9) and the check valve (2, 5), increase the diaphragm chamber (4), which contains the diaphragm, guide rod and its guide rod detection device, and the diaphragm connects the diaphragm chamber (4) The slurry conveyed inside is absolutely separated from the driven oil to avoid the mixing of the two. There are two kinds of diaphragm shapes, one is round, like an umbrella, and the other is tubular, with two ports open, and the outer edge of the two types has a flange as a sealing ring, which is used as a seal to prevent the mixing of the two transmission media. Diaphragm cavity (4) enters slurry from the lower end hole, and the upper end hole discharges slurry, and it is also possible to enter and discharge slurry through a hole in its lower part. The guide rod can be used to indicate the position of the diaph...

The invention belongs to a reciprocating type volume slurry pump, and relates to the technical field of plunger slurry pumps and diaphragm slurry pumps for conveying slurry. A plunger slurry pump is transformed into a piston isolation slurry pump, a cylinder with the diameter D0 of the plunger slurry pump is changed into an oil cylinder with the diameter D, and a diaphragm cavity and a guide rod cavity are added between the cylinder and a check valve. A new oil cylinder is fixed through a bolt hole of an original fixed cylinder or a check valve of a transmission box body and is installed on the transmission box body, and a piston or a plunger rod is in power connection with a pump. The cylinder is connected with the guide rod cavity and the diaphragm cavity; and the diaphragm cavity is connected with slurry feeding and discharging check valves. The check valve decides whether to continue to be used or be newly manufactured according to parameters and space. Oil and slurry are separatedby the diaphragm cavity, the piston or the plunger and a sealing ring are not damaged by the slurry, and a high-pressure water pump for sealing the plunger is not used; and the flow, the pressure andthe stroke frequency can be changed by changing the diameter of the cylinder and using a speed regulating device. The stroke frequency can be reduced, and the conveying pressure and the flow are improved; and the transmission box body has no need to be reprocessed. Electricity and water are saved, the service life of the check valve is prolonged, and maintenance is reduced.
Description
technical field [0001] The invention belongs to a reciprocating volumetric slurry pump and relates to the technical field of a plunger slurry pump and a diaphragm slurry pump for delivering slurry. Background technique [0002] For the structure and working principle of the plunger mud pump, see [ Figure 5 ], the motor drives the pinion shaft to rotate through a reducer or a belt, and the pinion meshes with the big shaft gear to rotate. The big shaft is divided into two types: eccentric wheel or crankshaft, which drives the connecting rod to do reciprocating motion, and the connecting rod drives the crosshead to do linear reciprocating motion . One end of the intermediate rod is connected with the crosshead, the other end is connected with one end of the piston or plunger rod through a clamp, and the other end of the piston or plunger rod is connected with the plunger or piston. The connecting rod drives the crosshead, intermediate rod, clamp, piston rod, plunger or piston...
